DETAILED DESCRIPTION

For the purposes of promoting an understanding of the principles of theinvention, reference will now be made to the embodiment illustrated inthe drawings and specific language will be used to describe the same. Itwill nevertheless be understood that no limitation of the scope of theinvention is thereby intended. Any alterations and further modificationsin the described embodiments, and any further applications of theprinciples of the invention as described herein are contemplated aswould normally occur to one skilled in the art to which the inventionrelates.

The present invention relates to an image capture device, system andmethod for use in capturing medical images. A collimator tube includesone or more integrated devices, such as a radio frequency transmitter, acamera, a frame grabber, or a transilluminator light. In one embodiment,the integrated devices are integrated within one or more walls of thecollimator tube. The integrated devices are used instead of or inaddition to an x-ray generator, which is coupled to the collimator tube.The camera is used to capture digital images. The camera is either acamera port for plugging in an external camera, such as an intra-oralcamera, or is wholly contained within the collimator tube. The radiofrequency transmitter transmits digital data to a computer. The framegrabber captures digital data for display on a display device. Thetransilluminator light can illuminate an area for visual inspectionand/or digital capture. A receptor holder includes a docking port fordocking a sensor that is used for digital x-ray image capture.

Referring to FIG. 1, one embodiment of the image capture device of thepresent invention is illustrated and indicated generally at 10. Imagecapture device 10 is operable to capture x-ray images. The image capturedevice 10 illustrated in FIG. 1 includes x-ray generator 12 andcollimator tube 14. Collimator tube 14 serves as the means for focusingx-rays produced by the x-ray generator 12. Alternatively oradditionally, collimator tube 14 also decreases scatter radiation and/ordecreases absorbed radiation, thereby lowering the patient's x-ray dose.In one embodiment, collimator tube 14 has a square shape in crosssection. Collimator tube 14 can also be rectangular, star, cross orround in cross section shape, as a few additional non-limiting examples.

In one embodiment, collimator tube 14 is fixed to x-ray generator 12 andcannot be removed. In another embodiment, collimator tube 14 isdetachable from x-ray generator 12, such as by removing one or morescrews or other securing means. Alternatively or additionally,collimator tube 14 can be a collimator tube of one shape that replaces apreviously attached collimator tube of a different shape. Onenon-limiting example includes detaching a round-shaped collimator tubeand replacing it with a rectangular-shaped collimator tube.

Collimator tube 14 has a tunnel 16 for emitting x-rays and a receptacle30 for receiving a sliding bar of a receptor holder. Collimator tube 14has an end 17 that serves one or more purposes. One purpose of end 17 isfor coupling a receptor holder to collimator tube 14. Collimator tube 14has one or more devices integrated within walls 18. In one embodiment,at least one integrated device is visible at least in part from end 17.In one embodiment, collimator tube 14 has a radio frequency transmitter20, a camera/port 22, a frame grabber 24, and/or a transilluminatorlight 26 integrated within one or more of walls 18.

Each of these integrated devices will now be described in further detailwith reference to FIGS. 1 and 2. Radio frequency (RF) transmitter 20 isoperative to send data captured with image capture device 10 to an RFreceiver external to image capture device 10. For example, the RFreceiver may be coupled to a remotely-located computer for the displayand/or processing of images captured by the device 10. As onenon-limiting example, RF transmitter 20 can transmit data captured withcamera 22 to an external computer. In this way, images captured by imagecapture device 10 may be downloaded to a computer system for currentand/or later use without the need to physically couple the image capturedevice 10 to the computer. This greatly improves the maneuverability andusefulness of the image capture device 10.

In one embodiment, the camera 22 is built into the collimator tube 14and is able to capture images visible from a lens or aperture formedinto the end of the collimator tube 14. In another embodiment, camera 22is an electrical port for allowing an external camera device to pluginto collimator tube 14 for transmission of data from the externalcamera device to the collimator tube 14 integrated devices. Onenon-limiting example of an external camera device includes intra-oralcamera 32 as shown in FIG. 3. The intra-oral camera 32 includes anelectrical plug 33 that interfaces with the camera 22 port in thecollimator tube 14 for transmitting data captured by the camera 32.Cameras 22 and 32 are operative to capture still images and/or videoimages in various embodiments. Provision of the external intra-oralcamera 32 allows for easy access to the inner regions of the patient'smouth.

In one embodiment, frame grabber 24 is operative to capture still and/orvideo images for display on an external video display device, such as ona television or a computer display, as is known in the art. Framegrabber 24 is integrally formed with collimator tube 14 to receive imageinformation from one of the image devices integrated with image capturedevice 10, such as camera 22/32 or the x-ray image receptor 44 (see FIG.4). The output of frame grabber 24 is preferably coupled to the RFtransmitter 20 for transmission of the frame data to a receivingcomputer and/or display device.

Transilluminator light 26 aids the image capture process by allowing fora light to be shined through a tooth, body or organ, as a fewnon-limiting examples. The light that is transmitted through the toothcan then be captured using the camera 22/32. For use with the camera 22formed integrally with the collimator tube 14, means must be providedfor directing the light from the transilluminator light 26 to theopposite side of the tooth as the camera 22. This may be done by use ofan appropriate mirror (not shown), or by making the transilluminatorlight 26 an external device that plugs into a port in the collimatortube 14, similar to the intra-oral camera 32. Additionally, thetransilluminator light 26 may emit light from the collimator tube 14 andthe light transmitted through the tooth may be captured using theintra-oral camera 32.

Various other device combinations are also possible, such as fewer oradditional devices than described herein, or a combination of thosedescribed. Power may be supplied to these devices by using the internalpower supply of the image capture device 10, as will be apparent tothose skilled in the art after reference to the above description.

In one form of the invention, collimator tube 14 has contact sensorreceptacles 28 that are used to mate an image receptor holder (see FIGS.8-10) to the collimator tube 14. Contact sensor receptacle 28 can be oneor more of various types, such as electrical, mechanical, optical, fiberoptic, magnetic or of other connection types as would occur to one inthe art. As one non-limiting example, contact sensor receptacles can beused to form a purely mechanical connection between the image receptorholder and the collimator tube 14. Alternatively or additionally,contact sensor receptacles 28 can be used to ensure a receptor holder isattached before firing x-ray generator 12. Alternatively oradditionally, one or more lights can be illuminated to indicate thestatus of the connection, such as green to indicate a proper connectionwith collimator tube 14 has been made and the x-ray generator is readyto fire, and red to indicate the x-ray generator is not ready to fire,to name a few examples. Alternatively or additionally, a light can beilluminated to indicate that a proper connection has been made, and thelight is not illuminated when a proper connection is not made.Alternatively or additionally, an audible sound can be emitted toindicate that a proper connection has been made. In one embodiment,contact sensor receptacles 28 are used with receptor holder 50illustrated in FIGS. 8-10. Alternatively or additionally, collimatortube 14 has a contact end receptacle 30 formed therein and operative toreceive a contact end of a receptor holder. In one embodiment, contactend receptacle 30 is used with the receptor holder illustrated in FIG.11.

In yet another embodiment, as illustrated in FIG. 4, collimator tubeadapter 34 is used to convert collimator tube 38 to a different shape.As one non-limiting example, collimator tube adapter 34 is used toconvert collimator tube 38 from a round shape to a rectangular or othershape. Collimator tube adapter 34 includes cone 35, cap 36, and spacer37. Cap 36 can slide to adjust cone 35 to different depths so cone 35can fit properly inside collimator tube 38. Various mechanisms can beused to lock cap 36 into a desired location on cone 35, such as usingdetents or a snap ring, to name a few non-limiting examples. Spacer 37is used to help secure cone 35 inside collimator tube 38, since cone 35is a different shape than collimator tube 38. Various types of spacerscan be used, such as a washer or an o-ring, to name a few non-limitingexamples. Cap 36 is operable to form a seal around end 39 of collimatortube 38.

Although not numbered on FIG. 4 to preserve clarity, in one embodiment,collimator tube adapter 34 has one or more devices integrated within itswalls. These devices can be integrated within walls of collimator tubeadapter 34 instead of or in addition to devices integrated in collimatortube 38. Collimator tube adapter 34 and collimator tube 38, when usedtogether, can include the same devices and perform the same functions asdescribed herein with respect to collimator tube 14 of image capturedevice 10 on FIG. 1.

As shown in FIG. 5, insert 40 is a step-down insert that can be insertedinto collimator tube 42 to make the image capture area smaller.Alternatively or additionally, insert 40 can be used to add integrateddevices to existing collimator tube 42. One non-limiting example of asituation in which insert 40 can be used is to capture an image moreprecisely on a smaller image receptor than collimator tube 42 wouldcapture alone. Alternatively or additionally, insert 40 can be insertedinto collimator tube adapter 34 of FIG. 4 to make the image capture areaeven smaller. Although not numbered on FIG. 5 to preserve clarity,instead of or in addition to the integrated devices included within thewalls of collimator tube 14 or collimator tube adapter 34, insert 40 canoptionally include one or more devices integrated within its walls.Insert 40 can optionally have at least one integrated device visible atleast in part from end 41. Details about these integrated devices andhow they function are described in detail in reference to FIGS. 1 and 4.Alternatively or additionally, insert 40 can be used to add one or moreintegrated devices to existing collimator tube 42 without reducing thesize of the image capture area any more than necessary to house theintegrated devices.

As shown in FIG. 6-7, in one embodiment, a collimator tube and/or x-raygenerator can rotate with respect to the other. Front end of x-raygenerator 43 can optionally include a circular or other path 44 withindentations 45. Collimator tube 46 mates with front end of x-raygenerator 43 with one or more detents 47 that lock and unlock into oneor more of indentations 45 when rotated along path 44. Circular or otherpath 44 can be a track or other types as would occur to one of ordinaryskill in the art so as to allow collimator tube 46 inserted therein toremain physically attached to the front end of x-ray generator 43 andthen click into position when coming into contact with one or moredetents 47. In an alternative embodiment, the indentations and path arepresent on collimator tube 46 and one or more detents are present onfront end of x-ray generator 43.

Referring now to FIGS. 8-10 with continued reference to FIGS. 1-2, afirst embodiment receptor holder 50 is illustrated. Receptor holder 50has a holder end 52 that is operative to hold an image receptor 54, suchas x-ray film or a digital charge-coupled device (CCD) sensor, as a fewnon-limiting examples. Receptor holder 50 has an adjustable bar 56 foradjusting the distance of holder end 52 from a connection end 58. In oneembodiment, connection end 58 has a square shape. Connection end 58 canalso be rectangular, star, cross or round in cross section shape, as afew additional non-limiting examples.

As shown in FIGS. 9 and 10, connection end 58 may have contact sensors59 that are operative to be connected with collimator tube 14 throughcontact end receptors 28 formed in collimator tube end 17. In oneembodiment, contact sensors 59 are used to ensure that the receptorholder 50 is attached to collimator tube 14 before firing the x-raygenerator 12. In this embodiment, contact end receptors 28 are formedwith sensors that determine when contact sensors 59 are insertedtherein. As one example, each receptor 28 may have two metallic elementsthat are short circuited by a conductive contact sensor 59 when theconnection end 58 is fitted to the collimator tube end 17. Couplingthese metallic elements to the firing circuitry of the image capturedevice 10 can prevent the image capture device 10 from being firedunless the receptor holder 50 is properly fitted, as will be apparent tothose skilled in the art from the above description. In one embodiment,receptor holder 50 is used to capture film-based x-ray images. Inanother embodiment, receptor holder is used to capture digitized x-rayimages. Alternatively or additionally, receptor holder 50 can be used tohold a mirror for reflecting an image to be captured with camera 22, orfor reflecting transilluminator light 26 for capture with camera 22.

Referring now to FIG. 11 with continued reference to FIGS. 1-2, a secondembodiment receptor holder 60 is illustrated. Receptor holder 60 has aholder end 62 that is operative to hold a digital sensor 64 or x-rayfilm 66. Alternatively or additionally, receptor holder 60 can be usedto hold a mirror for use with camera 22 or transilluminator light 26, asdescribed hereinabove. Holder end 62 contains a docking port 68 toenable connection of digital sensor 64, which includes a sensor end 70for electrical mating to docking port 68 of holder end 62. In oneembodiment, wiring 72 is connected to docking port 68 at holder end 62.Wiring 72 runs through adjustable bar 74 and connects to contact end 76.Receptor holder 60 has adjustable bar 74 for adjusting the distance ofholder end 62 from contact end 76. In one embodiment, adjustable bar 74can slide all the way out and separate from connection frame 78. Contactend 76 can be inserted into contact end receptacle 30 of collimator tube14 to couple receptor holder 60 to collimator tube 14.

Upon insertion of contact end 76 into contact end receptacle 30,connection frame 78 fits over end 17 of collimator tube 14. In oneembodiment, when digital sensor 64 is docked in docking port 68 andx-ray generator 12 is fired, digital data is captured using sensor 64and travels through wiring 72 to contact end 76 and to frame grabber 24of collimator tube 14. In another embodiment, digital data capturedusing sensor 64 travels through wiring 72 to contact end 76 and to radiofrequency transmitter 20 of collimator tube 14. In this embodiment, aframe grabber may be present in the remote computer.

In an alternate embodiment, receptor holder 50 (FIG. 8) and/or receptorholder 60 (FIG. 11) has an integrated radio frequency transmitter, suchas within the walls of the holder.

FIG. 12 illustrates an embodiment of the system of the presentinvention, comprising image capture device 10 with x-ray generator 12,collimator tube 14, and receptor holder (50 or 60) attached.

FIG. 13 illustrates an image capture device having an x-ray generator80, collimator tube 81, and receptor holder 82 of another embodiment ofthe present invention. Film alignment ring 86 of receptor holder 82 fitsaround outer perimeter 87 of collimator tube 81. In one embodiment,notches 89 in receptor holder 82 are tapered and/or indented to helpfilm alignment ring 86 align properly with collimator tube 81. Receptorholder 82 can be coupled to collimator tube 81 by magnetism when magnets83 of collimator tube 81 come into contact with conductor/magnetinterface metal snap ring 84 of receptor holder 82. Alternatively oradditionally, snap ring 84 completes the circuit between low voltageelectrical contact 85 and magnets 83, causing LED lights 88 toilluminate to indicate that receptor holder 82 is properly coupled tocollimator tube 81. Magnets 83 and/or electrical contacts 85 can belocated at one or more of various locations on outer perimeter 87 orother locations as would occur to one of ordinary skill in the art. Inone embodiment, collimator tube 81 is a replacement for a priorcollimator tube of a differing shape, such as a rectangular tubereplacing a round tube, to name a non-limiting example. Alternatively oradditionally, magnets 83, electrical contacts 85, and LED lights 88 canbe included in an adaptor that is attached to an existing collimatortube. In one embodiment, receptor holder 82 and collimator tube 81maintain a magnetic connection sufficient to couple them together but toalso to allow them to easily separate from each other upon contact, suchas with a doctor or patient touching receptor holder 82. Alternativelyor additionally, the positioning bar of receptor holder 82 has notchesthat allow the user to identify the distance at which the film waspositioned, such as to allow for re-taking another image in the futureat the same distance.
